Subject: [PATCH] Example of booted image versioning using CVS. We want to
 know, with what configuration (version of the image) each node was booted.
 Hence, we keep image definition files and postscripts in CVS. During image
 generation we create file /etc/IMGVERSION and fill it with CVS "$Id$" of
 files with image definition (.pkglist, .exlist, .repolist, .postinstall).
 Then, during boot, each  "CVS enabled" postscript adds one line to
 /etc/IMGVERSION. Then you can determine in any time what image you are
 running and what postscipts in which versions were run. /etc/IMGVERSION cat
 look like: smbec02n001(smbec02b01n01):~ #cat /etc/IMGVERSION #-- $Id:
